摘　　要：H两优991是用不育系HD9802S与恢复系R991配组育成的两系杂交稻新组合,连续3年在泰宁县大田乡进行烟后制种,具有高产、稳产的特点。介绍了H两优991亲本的特征特性,总结其烟后制种的高产技术。Two-line hybrid rice ＂H liangyou 991＂ was bred by crossing hybridization between sterile line＂ HD9802S＂ and re- storer line ＂R991＂. Seed production of ＂H liangyou 991＂ as post-tobacco rice was carried out in Datian Town, Taining County for continuous three years, and showed the character of high and stable yield. This paper summarized the characteris- tics of parent plants of ＂H liangyou 991＂, its high yield seed-producing techniques after tobacco cropping season.
